Authorities searched for a gun owner who fled after his weapon fired by accident at Atlanta’s airport, sending terrified travelers bolting onto the tarmac on Saturday, halting flights during the busy Thanksgiving holiday period.

Three people suffered non-life-threatening injuries after the 1:30 p.m. shot in the security screening area at Hartsfield-Jackson Atlanta International Airport, the Transportation Security Administration (TSA) said in a statement.

Some two hours later, officials gave an “all-clear” and flights resumed, the airport said on Twitter.

An arrest warrant was issued for the 42-year-old gun owner, named by police as Kenny Wells.

He was being sought on charges of carrying a concealed weapon at a commercial airport, possession of a firearm by a convicted felon, discharging a firearm and reckless conduct, Atlanta Police Major Reginald Moorman told a news conference.

The gun discharge occurred when a screening checkpoint employee was conducting a bag search “due to a prohibited item identified by the X-Ray,” the TSA said in a statement.

“He advised the passenger not to touch the property, and as he opened the compartment containing the prohibited item, the passenger lunged into the bag and grabbed a firearm, at which point it discharged,” the TSA said.

The gun owner fled from the airport, although “he was not allowed to go,” airport spokesman Andrew Gobeil told CNN.

“Because he was in the process of being screened, we have all his information,” Gobeil said.

Immediate fear that an active shooter had opened fire panicked the crowd, which rushed out of the terminal onto the tarmac.

“More and more people started running – there was screaming,” said traveler Erika Zeidler, who sent photographs to CNN showing dozens of people scrambling onto the tarmac, some pulling suitcases.

Police said one person requested EMS after experiencing a fall “in the atrium of the airport, which is not in the same area of the security check point, and two others complained of a shortness of breath.”

Hartsfield-Jackson was the world’s busiest airport in 2021, according to aviation analytics provider Official Airline Guide (OAG).

The Atlanta airport was expected to be particularly busy during the Thanksgiving travel period, with prepandemic-size crowds expected at security checkpoints from Friday, November 19 through Sunday, November 28, the TSA said.

“Officials have given an all-clear for #ATLAirport and normal operations are beginning,” the airport tweeted at 3:24 p.m.

A record number of firearms were seized at US airport checkpoints in just the first nine months of 2021, the TSA said.

Nationwide, TSA officers have stopped 4,495 airline passengers from carrying firearms onto their flights, surpassing the 4,432 firearms caught throughout 2019.

In Atlanta alone, there were 450 firearms detected at airport checkpoints in 2021.
